Abstract (en)
[origin: EP1864710A1] When making moisture content adjustment by adding liquid such as water to a raw material such as pulverulent material including bentonite, uniform mixing of the liquid such as water with the raw material is given with relatively simple facilities, moisture content adjustment of a large quantity of raw materials is attainable, and besides, a material having satisfactory performances such as impermeability is obtainable through uniform moisture content adjustment. Within a mixing tank (1) configured with a normal powder mixer kept at low temperatures, pulverulent bentonite (A) and fine granular ice (B) are stirred and mixed. Stirring and mixing of the fellow pulverulent materials are adapted to uniformly mix the pulverulent bentonite (A) and the fine granular ice (B), enabling uniformly moisture content-adjusted bentonite to be obtained. A liquid-nitrogen gas bomb (21), for instance, is connected to the mixing tank (1), causing the inside of the mixing tank to be kept at low temperatures with nitrogen gas supplied from the bomb, before putting the prepared fine granular ice (B) through an inlet port (20).
